Video - Alexander Skarsgard joins stars at Comic-Con

Alexander Skarsgard, the Swedish 'True Blood' actor, spotted out-and-about during Comic-Con 2011 in California. Wearing a woolly hat with dark sunglasses, Skarsgard made his way around the San Diego Convention Centre before being mobbed by fans looking for autographs.

The actor was one of many high-profile celebrities getting involved at the comic book convention this year. Star of 'The Amazing Spider Man' Andrew Garfield made an appearance, as did 'original' Batman Adam West. 'Star Trek' actors Patrick Stewart and William Shatner were also in attendance
